Add option to include prefix and suffix in log file name for broker
-------------------------------------------------------------------

                 Key: QPID-13
                 URL: http://issues.apache.org/jira/browse/QPID-13
             Project: Qpid
          Issue Type: New Feature
          Components: Java Broker
         Environment: All
            Reporter: Marnie McCormack


An end user has requested the ability to use the process id in the log file name for the broker.
This could make testing easier for the test team here by allowing them to identify logs with
processes.

In fact, it would probably be better to allow users to set any system property that they qish
to be used in the log file name. This would also avoid our current scenario where two brokers
on the same host will log to the same file, rendering it unreadable in any useful way.

So, if they set a given system property name at runtime i.e. logprefix or logsuffix then the
log4j.xml config will pick that up and use it.

If these properties are not set then the log name will remain as it currently is i.e. qpid.log.
However if they set, for example, the prefix to the pid (2701) and the suffix to the servername
(myhost) then the log name could be something like 2701qpidmyhost.log.

To set the pid as a system property need to add a -D to the java command that starts the broker
i.e. -Dlogprefix=$$ (on unix). Might be more complex on linux and involve reading the /proc/self/stat
file. More details on this shortly .......
